SVAMITVA SCHEMEPROCEDURE/PRACTICE ADOPTED

inUTTAR PRADESH (UP). - By Rajiv Srivastava

Director Uttar Pradesh (East) Geo-Spatial Data Centre

OUTLINE

• Inroduction

• Pre-Drone Survey

• Drone Survey

• Post Drone Survey

• Challenges & Way forward

INTRODUCTION

• MoU signed on 8th June, 2020.

• Earlier 1,08,000 villages in all 75 districts were to becompleted which is now revised to 69,766 villages.

• Huge task of UP is being done by Lucknow, Delhi &Dehradun offices of SoI. Few activities are also beingcontributed by other SoI offices located at differentplaces of India.

• Presently, nearly 60 drones teams are engaged indifferent districts of UP.

• Drone Survey (Flying) of 30,861 Villages has beencompleted till 11th Sept’ 2021.

PRE-DRONE SURVEY• Collection of notified list of villages with approxcoordinate/s of abadi areas.

• Collection of corresponding Revenue Maps withred line marking around abadi areas alonwithbhulekh document (Khatauni).

• Ground control work i.e. coordinate provision i/ccheck point for Drone Survey.

• Correspondence for Civil Airport/Air Forceauthorities for smooth Drone Survey.

• Creation of kml/mission planning for DroneSurvey.

DRONE SURVEY• Ensure from village representative of StateGovt that chuna marking of village is done.

• Drone Survey in PPK mode is carried outafter ATC approval as per SoP.

• Checking of flying data.• Geo-tagging of drone captured data.• Storing of raw data in external hard disk tobe sent to SoI office.

POST DRONE SURVEY

• Feature extraction(FE1.0) & handing over of Map1.0 print in to districts for attribute entry like parcel/property no, new feature etc.

• Feature Extraction(FE2.0) and uploading of final property data on UP State portal.

• Processing of geo-tagged drone data & creation of ORI and DEM.

FINAL DATA UPLOADING ON UP PORTAL

Filled Form 5 Submitted by SOIBlank Form 5 Received from State Govt.

CHALLENGES & WAY FORWARD

➢ Biggest challenge is handing over of paper print ofMap1.0 to districts. It also affects the return ofMap1.0 after attribute entry.

➢ SoI has made a mobile/tablet based applicationwherein Map1.0 data will be available through WebServer to the user.

➢User can add attribute directly in mobile/tabletwhich will save lot of time & money.

Madhya Pradesh Geo Spatial Data Centre

SVAMITVA (Survey of Villages and Mapping with Improvised Technology in Village Areas) scheme is initiative of the Ministry of Panchayati Raj (MoPR)

Main objective of SVAMITVA Scheme as under:-

To bring financial stability to the citizens in rural India

Creation of accurate land records for rural planning

Determination of property tax

Creation of survey infrastructure and GIS maps

To support in preparation of better-quality GramPanchayat Development Plan (GPDP)

To reduce property related disputes and legal case.

SAARA (Smart Application for Revenue

Administration) Portal:

Data Sharing, Data Augmentation and Data Application is envisaged through this portal

Mutually decided vector data template in which data is to be presented and archived

Data Template :

The vector data is broadly classified in two categories and presented in a consolidated GDB with UTM projection:

1. Property Parcel

2. Other Features

Scheduling Drone Flying

➢ Prior sharing of Drone Flying Schedule facilitate theconcerned administration in:• Registering the case on SAARA Portal• Chunna / Lime Marking thereafter

Field Work: Chunna Marking

13-09-2021


Determining the outer limits of the Abadi Areaby

lime/Chunna marking

To separate Abadi area from the limit of Non Abadi area as

per the revenue records

Determining the limits of Abadi plot area by lime/Chunna

marking

Limits of property of residents including their built up and

non built up area such as fencing, should be marked by

chunna atleast 2 days before the Drone survey.

Ensure that Govt/Public property has perfectly been marked.

After Chunna Marking by state officials, field hand will

verify for any missing Khasra for chunna marking prior to

flying.
